M2T vs MP4

M2T vs MP4

Postby Svein Berger » Sat Aug 23, 2014 11:46 am

Hi all,
I wonder what is the difference between these extensions.

I want to export some edited AVCHD footage for use in an other project.

Yep. As Peru says, they're very different formats.

MP4s are usually for displaying video on a computer. It didn't used to be a format for editing, but since more and more camcorders and smartphones are using it, it's also become a format that video is shot on. MP4s can be any of a number of sizes and resolutions.

M2Ts are video from high-def camcorders, and it's of a bit more density and quality than MP4s. It's the preferred format for editing high-def and AVCHD video.

MP4 and M2T are container formats. The contents are defined by the codec used and the selected codec property settings. M2T is a subset of M2TS more closely associated with AVCHD and supports only H.264/MPEG-4 AVC. As Steve said, MP4 had its roots in computers rather than tv and optical disc players. But, the standard has evolved and MP4 is becoming extensively used in Internet streaming and mobile video. When you create an mp4 container with the H.264/MPEG-4 AVC codec, you are using the same codec as the M2T and the two formats will have essentially the same video quality assuming you have used like settings.

Thanks Peru, Steve and Bob.

It made it clear to me that I should save my project in M2T format, if I use it for further editing.
And Bob, detailed and explanatory answers as always, thanks.
